Chemistry as Emergent Quantum Physics?

A physical phenomenon may be called emergent if it is a non-obvious consequence of the assumptions of a physical theory revealed by symbolic or digital computation, and can then be seen to be a consequence of theory + computation, where computation in adds essentially new theory. 

A key example is turbulence which is an emergent aspect of solutions of Euler's equations for incompressible inviscid fluid flow computed as best possible in a specific sense specified in the book Computational Turbulent Incompressible Flow. 

Let us ask:

• Does chemistry as science of molecules composed of atoms, emerge from quantum physics as science of atoms? 

Assume first that quantum physics is textbook Standard Quantum Mechanics StdQM. A physicists in the foot steps of Dirac will say that chemistry is applied quantum physics and so that 

• Chemistry emerges from StdQM, in principle.                                                 (1)

A chemist will object and say that 

• Chemical bonding as essence of chemistry does not emerge from StdQM.      (2)   

Let us assume that (2) based on experience is true, noting that (1) is speculation. 

But if (2) is true, then chemistry needs more of physics than what is in StdQM, but exactly what that is not clear. 

We now compare with RealQM as an alternative to StdQM coming with the following ambition:

• Chemistry and chemical bonding emerges from RealQM.                                  (3)

RealQM has computational form of linear computational complexity, which allows complex chemistry to emerge from computation with RealQM, without need of any extra physics.  Want to try?

Recall that RealQM is ab initio, with mesh resolution as only parameter, which means that all theory is already within RealQM in transparent form.

This is not the case for StdQM, where computation implicitly adds new physics without transparency.
